Margarita Ibarra prays as members of LUPE gather during a news conference and vigil Thursday Nov. 1, 2012, on the corner of Farm-to-Market Road 2221 and Mile 7 near La Joya, Texas. The Texas trooper who fired on a fleeing pickup truck from a helicopter near the U.S.-Mexico border, killing two illegal immigrants hiding in the bed, has returned to work but in a different role, the state Department of Public Safety said Thursday. The announcement came less than an hour after the American Civil Liberties Union and local civil rights organizations gathered near the site of the Oct. 25 shooting to demand an investigation by an independent body outside the agency. Currently, the Texas Rangers, an elite force within DPS, is leading the investigation. (AP Photo/The Monitor, Gabe Hernandez)

FILE - In this May 1, 2012, file photo, Viviette Applewhite, 93, a plaintiff in a lawsuit against Pennsylvania's tough new voter identification law, speaks in a video played during a news conference in the Pennsylvania state Capitol in Harrisburg, Pa., as one of her lawyers, Witold J. Walczak of the American Civil Liberties Union. Before voters get a say in this year's presidential race, lawyers and judges are having theirs. A series of ongoing court battles in several vital states may determine over the next several weeks everything from how people cast their votes, when polling locations will be open and what ballots will look like. Many of the cases have a partisan bent, with rulings potentially tipping the scales slightly in favor of Democrats or Republicans. The legal battles have entered an urgent phase, with only two months to go before the election and just a few weeks before military and overseas absentee ballots must go out. Pennsylvania attorneys recently filed briefs arguing whether an appeal on the state's strict voter ID law should be held in September or October. Opponents won a mid-September court date, which is late even by their standards. "This is by no means impossible, but certainly the closer you get a decision to Election Day the harder it is to make changes," said Walczak. (AP Photo/Marc Levy, File)
